How do I...?

I am creating a futuristic top down 2d scroller in TorqueX2D and, I have created a really cool animated tank sprite, the base is a static sprite with the turret being a 35 cell animation, how do I set the tank's turret to "look at" and fire upon the Player?

This would also be used for other turrets.

(edit: I forgot to mention what engine I am using)
